I am building single page application and I would like to know user's identity. We have Active Directory in our intranet but I don't know much about it. I am able to use code like this to verify username and password.
using(PrincipalContext pc = new PrincipalContext(ContextType.Domain, "YOURDOMAIN"))
{
bool isValid = pc.ValidateCredentials("myuser", "mypassword");
}
In fact that is everything I need from the Active Directory side of thing. So I could create some AuthorizationFilter with this code but this would mean that username and password must be in every request. I would like to send username and password only once and then use some token for authorization. So there should be some token provider inside my server-side application.
I am building this application from scratch so I can use the latest .net technologies. I found that there are some Owin middlewares which are handling tokens, cookies and OAuth. Could anything of that help me?
